The diagnosis was Salter Harris Type III fracture of the fourth middle phalanx.

Teenager in a motor vehicle accident

CT of mastoid fracture — Axial CT without contrast of the maxillofacial bones shows a linear lucent line through the lateral aspect of the right mastoid bone with resultant opacification of the mastoid air cells. There was associated diastasis of the right lambdoid suture.

The diagnosis was right mastoid fracture.

Infant with a maculopapular rash on the buttocks

Radiograph of syphilis — AP radiographs of the bilateral lower extremities show diffuse, thick, symmetric periosteal reaction bilaterally. There is a suggestion of a metaphyseal notch on the proximal medial right tibial metaphysis (Wimberger corner sign).

The diagnosis was syphilis.

Female teenager with right lower quadrant pain

MRI of unicornuate uterus — Sequential coronal T2 MRI without contrast images of the pelvis show the uterus to consist of a single fluid filled dilated right horn (above) which empties into the vagina (below).

The diagnosis was Mullerian duct anomaly in the form of right unicornuate uterus.

Infant with bilious vomiting

Upper GI of malrotation with midgut volvulus — AP image from an upper GI exam shows the contrast filled stomach in the upper right of the image emptying into the duodenal bulb which is just to the right of the spine. The position of the duodenal-jejunal junction is not well defined and it may be in the right upper quadrant or in the left upper quadrant. In either case, it is well below the level of the duodenal bulb and therefore is malpositioned.

The diagnosis was malrotation with midgut volvulus.

Toddler with new coughing and wheezing

CXR of airway foreign body in right mainstem bronchus — Inspiratory CXR (above) shows normal symmetrical aeration of the lungs bilaterally. Expiratory CXR (below) shows asymmetrical increased aeration (seen as increased lucency) of the right middle and lower lobes compared to the remainder of the lungs due to air trapping in the right middle and lower lobes.

The diagnosis was airway foreign body due to a peanut in the distal right mainstem bronchus.

Young adult with a gastrojejunostomy tube and chronic abdominal pain

CT of gastrojejunostomy tube causing duodenal-jejunal intussusception — Axial (above) CT with contrast of the abdomen shows a round soft tissue mass to the right of the vertebral body that has a target sign appearance and that has a jejunostomy tube coursing in the center of it.

The diagnosis was gastrojejunostomy tube malfunction due to the formation of a duodenal-jejunal intussuception forming around the tip of the jejunostomy tube.
